.UN ETED ST E N ARESON, F PORTLAND, OREGON, ASSIGNOB TO N RTHERN IMPLEMENT FACTURING. COMPANY, f or KING COUNTY, WASHINGTON f MANU- AUToMorrvE WHEEL' i Application iled September 4..1928.'.Seria1`No.r303,779.

My invention relates to demountable rims' for automotivel wheels and'to removable metallic tires for metal felloe wheels,v and pro` vides simple means for the removaly of the rim and tires from the wheel.

The invention in its preferred embodiment consists of a two-piece rim element adapted to coast with each other, one of which is rela- Y tively fixed to the wheel and theother being l@ adaptedV to partial rotation' relative tothe felloe and during such rotation to be` tightcnedl or loosened relative thereto so that a locking engagement is maintained or broken between the felloe andr the' rim` structure; simple means being provided for the partial rotation of the rim relative to the fell'oe yby t In these drawingsa short bar.

The rim is secured to the felloe by a lock.-L

` ing wedge inserted in an aperture formed in and between the inner periphery of the rim and the wheel felloe, one half ofthe aperture being` formed in the rim and the other half in the .fel-loe. The rim is rotatedpand tightened upon the felloe byuse of the short bar until.

the two halves ofthe aperture are in precise alignment to permit the insertion of the locking wedge which is prevented from working out by a cover spring provided on the under-v4 side with a pressed protrusion fitting a corresponding recess in the head of the wedge.

A further object of my invention is to effect a more simplified construction, and one that is adapted to all forms of automotive y wheels. either of the disc or artillery type,

`to enable the removal of rims or tires with greater facility and more speedily, and without the use or removal of threaded elements of any kind.

Heretofore in devices of this kind it has p been the general practice to maintain the rim in tight working relationship with that of the wheel felloe by threaded elements of various forms. The removal of the same can only be accomplished by the unthreading of the 'threaded elements by wrenches of various type. This requires a substantial amount of time and physical effort to accomplish the result. With my new and improved construction no threaded elements are required. The same results may be easily and quickly accomplished through the use of a simple locking wedge adapted to be inserted within an aperture in the oppositely disposed surfaces of they elements to be locked together.-

A further obj ect of my new and improved device resides in economy of construction with interchangeable parts provided.

l/Vith these and incidental' objects in view,

the invention consists in certain novel fea-` tures of construction and combination of parts, the essential elements of which are set forth in the appended claims, and a preferred yform of embodiment of which is hereinafter shown with reference to the drawings which accompany and form a part of this specification.

In preferredk embodiment I preferably form.

my wheel structurek as a one piece discy member having a central hub 1, sides Qand a turned edge 3 to which the felloe 4 is riveted.Y A peripheral flange 5 isdisposed upon one number of locking elements, as the number will depend upon the weight of the car with which the same is to be used and the diameter of the wheel, as it will be apparent that the heavy duty truck will require a modified structure to that of the light pleasure car.

The rim 10 is adapted to the elloe of the wheel and is made to engage upon its one side with that of the peripheral flange 5 of the f, wheel member. The rim may be made in two pieces and provided with a removable element 11 having a central portion 12, one side of which upwardly extends into a tire flange 13 and on the inner periphery is disposed an extended flange 14 engaging with the vflange 6 of the felloe when in place.

The inner wall ot 12 is made to engage with the opposite rim 'flange section 15 which contacts with the peripheral flange 5 of the wheel. The rim sections are secured together by a plurality of locking pins 16 disposed upon the inner surface of the removable element 11 of' the rim 10 which pins are made to engage the locking lugs 17 of the opposite rim section, as shown in Figs. 4 and 5, wherein a section of the rim is shown assembled.

The lugs 17 are prevented from backing oil' the pins 16 by the lever 18 contacting the back of the lugs 17. Figs. 4 and 5 show this.

To disassemble the rim only requires the moving of the lever 18 to the ofi position and a partial rotation of the rim element 13 to permit the separation of the rim sections 13 and 15.

The rim is secured to the wheel by mountingit upon the felloe and circumferentially rotating it until the lugs 9 oi the rim are in full engagement with the locking grooves 7 of the felloe. It is then tightened by the use of a short bar B inserted through a hole 19 in the felloe of the wheel and the end of the bar is made to contact the lug 2() formed f on the inner periphery of the rim 10 enabling the rim to be pried around upon the felloe until two halves of an aperture 21 cut respectively in the flange 6 oi the felloe 4 and the flange 14 of the rim 10 are in exact alignment.

The rim 10 is then locked upon the telloe 4 by the insertion of a locking wedge 22 in the aperture 21. The locking wedge 22 is prevented from working out of the aperture 21 by provision of a cover spring 23 as shown in Fig. 6, which also shows in elevational section the locking wedge 22.

Figure 8 shows in section the wedge 22 and cover spring 23. Figure 7 shows the two halves of t-he aperture 21 in exact alignment and the wedge 22 in place.

Toremove the wedge 22 there is provided a hole 24 in the side of the clloe to permit the insertion of a small bar to pry out the wedge.

This hole is fitted with a cover plate 25, as shown in Fig. 7.

While the form of mechanism herein described is admirably adapted to fulfil the objects primarily stated, it is to be understood that it is not intended to confine the invention to lthe one form of embodiment herein shown and described, as it is susceptible of embodiment in various forms, within the scope o the claims which follow.

Having now particularly described my invention what I claim is:

1. A wheel having a radially outwardly flanged felloe, a rim having a radially inwardly projecting flange to cooperate with thefelloe flange, said flanges each having one-half of an aperture, which halves when in alignment will constitute a wedge receiving aperture, a locking wedge pivotally held in one of the halves of said aperture and adapted to be moved into the other half of the same, and a member pivotally secured to said felloe and adapted to overlie said wedge to retain it in place, and means securing said rim to said felloe by circumferential movement in respect thereto.

2. A wheel having a radially outwardly flanged felloe, a rim having a radially inwardly projecting :flange to cooperate with the felloe flange, said flanges each having 'one-half of an aperture, which halves when in alignment will constitute a wedge receiving aperture, a locking wedge pivot-ally and removably held in one of the halves of said aperture and adapted to be moved into the other half of the same, and a cover spring secured to said felloe and adapted to overlie said wedge to retain it in place, and means securing said rim to said felloe by circumferential movement in respect thereto.

In testimony whereof I aflix my signature.
